3 Claims. (01. -1235) My inventicn relates to improvements in combined wire stretchers and splicer's;

The invention is designed with the particular purpose in view of providing a compact, small device of this character which is operative to stretch taut substantially any kind of wire, at any point of break inthe line, and without attachment to a fixedpart; such as a post, and which is adapted for easy and quick manipulation to splice the loose ends of the wire together in taut condition so that no slack will occur in the line after the'splice is made.

Another object'is to provide a device of the character andfor the purpose above set forth which is adapted for making different types of splices.

Other and subordinate objects are also comprehended by my invention, all of which, together with the precise nature of my improvements will be readily apparent when the succeeding description and claims are read with reference to the drawings accompanying and forming part of this specification.

In said drawings:

Figure 1 is a view in plan of the combined stretcher and splicer embodying my improvements,

Figure 2' is a view in side elevation,

Figure 3 is a detail view in longitudinal section taken on the line 33 of Figure 2 and drawn to an enlarged scale,

Figure 4 is a fragmentary view in longitudinal section taken on the line 4-4 of Figure 1,

Figure 5 is a view in transverse section taken on the line 55 of Figure 1 drawn to an enlarged scale and looking in the direction indicated by the arrows, and

Figure 6 is a View in perspective of one of the clamping members.

Referring to the drawings by numerals, the stretcher and splicer of my invention comprises, as its basic member, a stock i having at one end a barrel section 2 provided with a longitudinal extending top groove 3 therein, an opposite end 4 similarly grooved, as at 5, and a pair of laterally spaced side bars 6 intermediate said ends forming, together with the latter, a rectangular opening I. A short shaft 8 is rotatably mounted at its ends in said side bars 6 and has fast thereon a Winding drum 9 fitting between said side bars to extend transversely of the grooves 3 and 5. A hand crank I0 is provided on one end of said shaft 8 for operating the same and the drum 9, said crank comprising a straight two-part telescopic section II pivoted at one end to the shaft 8, as at l2. and a hand-grip section it pivoted, as at M, to the other end thereof, the arrangement being such that said sections may be swung into angular relation to form a crank extensible at will and swingable into different angular positions to said shaft 8 for convenience in manipulation of the crank, or swung one on the other into a straightened-out position for location alongside the stock in an out-of-the-way position. A ratchet wheel [5 is fixed on one end of the drum 9 and a holding dog 16 pivoted on one side bar 6, as at I 1, for releasably engaging said wheel 15 to hold said drum against rotation in one direction.

Extending from the barrel section 2 is a short intermediate barrel section [8 having a longitudinal groove l9 therein, similar to grooves 3 and 5, and similarly extending from said intermediate barrel section i8 is a terminal barrel section 20 provided with a longitudinally extending top groove 2| therein similar to and I9.

The barrel sections 2, I6 and 29 are attached together for relative rotation, substantially axithe grooves 3, 5

ally, by the following means, it'being understood that barrel 2 is rotated by rotation of the stock l. The attaching means comprises a pair of end trunnions 22 and 23 on the intermediate barrel section I3, grooved as at 24 and 25. in alignment with the groove I9 of said section and having ent larged outer ends 26, said trunnions being journalled in similarly shaped sockets 21 provided in the barrel sections 2 and 20. The terminal barrel section 20 has extending from its outer end a transversely grooved stud 28 for the attachment of wire thereto in a manner and for a purpose presently seen.

Each barrel section 2, l8 and 2D has slidably mounted therein a transversely extending clamping member 29 having an end-wise movable shank 30 extending through a transverse bore 3! in the bottom of the section, to one side of the groove of the section, and provided at one end with a right angled clamping finger 32 overlying the groove of the section and movable under endwise movement of the shank in opposite directions into and from clamping relation to the bottom of said groove. A transverse groove 33 in one side wall of each barrel section 2, l8, and 29, accommodates the shank 30 of the related clamping member 29.

The shank of each clamping member 29 is endwise movable through the medium of a hand lever 34 having one end pivotally and slidably mounted in a bracket 35 secured to the related barrel section by screws 36, the mounting comprising a stud 31 on the lever and a slot 38 in said bracket 35 extending transversely of the barrel section, and the shank 30 being connected to said lever 34 through a pin and slot connection 39, the arrangement in this instance being such that swinging movement of the lever 34 in opposite directions relative to the barrel section will cause the clamping finger 32 of the crank 30 to move into and from the above described clamping relation and the stud 31 may be shifted in the slot 38 to vary the leverage exerted by the lever 34 as occasion may require. A groove is formed in the shaft 8 adjacent to the crank ID for use as a wire cutter.

Referring now to the operation, to stretch and form one type of splice in the ends of a broken. wire, one end 4| of the wire, shown in dotted lines in Figure l, is laid from the end 4 of stock in the grooves 5, 3, l9 and 2| of said stock I and barrel sections 2, l8 and 20, said sections being first rotated to align said grooves, and the extremity of said end of the wire being looped around the stud 28 in the groove thereof. The other end 42 of said wire is laid from the reverse direction in the grooves 2|, l9 and 3 of the barrel sections 20, I8 and 2, and its extremity wound around the drum 9, said end 42 being passed through the loop wound on the stud 28. The crank i0 is now operated, whereupon the ends 4| and 42 will be drawn taut side by side. The clamping members 29 are now operated through the medium of the hand levers 34 to move the clamping-finger 32 into clamping engagement and thereby clamp the ends 4| and 42 to the bottom of the grooves 3, I9 and 2|. Next, the intermediate barrel section H! is held stationary and the terminal barrel section 20 rotated in one direction while the stock together with the barrel section 2, are rotated in. the opposite direction. These operations twist said ends 4|, 42, into a tight splice while said ends are taut, thus leaving the wire taut when the apparatus is detached as by releasing the clamping fingers 32 in a manner which will be understood without explanation. In holding the intermediate barrel section |8 stationary and rotating the terminal barrel section 20 and the stock the hand levers 34 are utilized as hand grips.

Various other types of splices may be made with the described invention, but, the foregoing description of the manner in which one form of splice is made will sufilce to convey an understanding of the use of the invention.

The foregoing constitutes a detailed description of a preferred embodiment of my invention, but it is to be understood that the present disclosure is illustrative rather than restrictive and that right is herein reserved to modifications in the structural details and relations of the parts described falling within the scope of the subjoined claims.

What I claim is:

1. In a wire stretcher and splicer, a stock, a plurality of barrel sections at one end or said stock disposed in end to end relation and longitudinally grooved to receive therein the ends of a broken wire extended therethrough side by side from opposite directions, respectively, and manipulative means on each section for clamping the wire ends to the wall of the groove thereof,

said sections being relatively rotatable, whereby said clamped ends may be twisted together in spliced relation.

2. In a wire stretcher and splicer, a stock, a plurality of barrel sections at one end of said stock disposed in end to end relation and longitudinally grooved to receive therein the ends of a broken wire extended therethrough side by side from opposite directions, respectively, and manipulative means on each section for clamping the wire ends to the wall of the groove thereof, said sections being relatively rotatable, whereby said clamped ends may be twisted together in spliced relation, said manipulative means com prising operating levers, respectively, adapted for use as hand grip members in rotating the sections. y

3. In a wire stretcher and splicer, a stock, a plurality of barrel sections at one end of said stock disposed in end to end relation and longitudinally grooved to receive therein the ends of a broken wire extended therethrough side by side from opposite directions, respectively, means on the outer end section. for anchoring one wire end thereto, means on said stock adapted for the attachment of the other wire end thereto and operative to wind up said end, and manipulative means on said sections, respectively, for clamping said wire ends to the wall of the grooves thereof, said sections being relatively rotatable, whereby said clamped wire ends may be twisted together in spliced relation.
